Patent GB-610314-A (GB)
Title: Improvements relating to the construction of rotors for compressors and turbines
IPC: F01D5/06
Filed: 1945-01-16
Abstract: 610,314. Turbine rotors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and McLEOD, R. C. Jan. 16, 1945, No. 1355. [Class 110 (iii)] A rotor for a multi-stage axial flow compressor or turbine comprises a plurality of axially spaced wheels held together by a compressive stress, each wheel carrying in axial root slots at least one row of blades fabricated separately from the wheel, abutment means located radially inwardly of the blade roots but near the wheel periphery to transmit the whole of the compressive stress, and shroud rings between the peripheries of adjacent wheels to fill the spaces between the adjacent blade rows and to locate the latter axially. The rotor shown consists of a plurality of wheels 3, each carrying peripherally in axial root slots separately fabricated blades. The wheels are held together in a pack by a tie-bar 4 passing through the centres of the wheels and having a tensioning nut 5 at one end of the rotor and a head 6 at the other. The wheels 3 have near the hub complementary interengaging dogs 8 to ensure the transmission of torque between the wheels. These dogs have a clearance in the axial direction so that they do not transmit any of the compressive stress applied by the tie-bar, the whole of which stress is transmitted radially inwards of the blade roots by the inner flanges 10 of I-section rings 9. The flanges 10 and peripheral shoulders 11 on the wheels 3 abut in the radial direction so that a part of the centrifugal force on the ring is transmitted to the wheels. An additional radial location of the wheels 3 to one another is provided by the ribs 12. These ribs also have axial clearance between them so that no compressive stress is applied through them. The outer flanges 13 of the I-section rings 9 form a shroud in axial register with the peripheries of the discs. There is a clearance between the flanges 13 and wheels 3 so that no compressive stress is applied through the flange, but these flanges are close enough to the wheel to ensure location of the blades. The central bores of the wheels 3 are provided with rings 14, split for ready insertion to form a step for use when dismantling the rotor. The internal cavities of the rotor may be used for cooling purposes. To increase the elasticity of the tie-bar 4 it is made in three parts, a central member 4, an intermediate sleeve 4a and an outer sleeve 4b. The intermediate sleeve 4a is attached to the sleeve 4b at the nut end and the central member at the head end.
Patent GB-397370-A (GB)
Title: Improvements in or relating to clutch operating devices for motor vehicles
IPC: B60K23/02
Filed: 1933-01-16
Abstract: 397,370. Operating clutches. KNORRBREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, and JANDER, H., 7, Essenerstrasse, both in Berlin. Jan. 16, 1933, No. 1461. [Class 80 (ii).] In an engine-suction servomotor for operating the clutch of a motor vehicle, one end 25 of the servo is in constant communication with the engine intake manifold 9 while the other end 24 is alternatively connected to the atmosphere through a port 15 and to the manifold 9 through a pipe 8 containing a ball valve 11 loaded by an adjustable spring 12, such alternative connection being effected by a spring- loaded electromagnetic valve 14 controlled by the accelerator pedal 21. The piston 2 of the servo is connected to the clutch pedal 5 by a rope or chain 4. On release of the pedal 21. causing closure of a switch 19, the valve 14 is moved to open the port 15, whereby the clutch is released. On depressing the pedal, during the first part of the movement the switch is opened, so that the valve 14 returns under the action of its spring to close the port 15 and establish communication between the chamber 24 and pipe 8. The piston 2 now commences its clutch-engaging stroke, but upon initial engagement of the clutch parts a state of balance, depending on the adjustment of the spring 12, is reached, and the rate of the final engaging movement corresponds to the rate of opening of the throttle.

Title: Improvements in or relating to control systems for effecting the energisation of twoalternating current load units
IPC: H02P1/58
Filed: 1957-01-15
Abstract: 803,230. Control systems for consumption apparatus. WESTINGHOUSE ELECTRICINTER NATIONAL CO. Jan. 15, 1957 [Jan. 23, 1956], No. 1485/57. Class 38 (4). [Also in Group XXXVII] Induction motors M1, M2, are started in sequence with the aid of a common reactor R which is connectable to the primary windings of the motors in turn. To start the motor M1, a selector switch SW is moved to its upper position and a push-button 3 is depressed, whereby contactor 11 is energized. This causes the energization of the actuating-coil 13 of circuit-breaker CB2. Contactor 21 is then operated to energize the actuating coil 24 of circuit-breaker CB1 so that the motor M1 connected to the supply-lines through reactor R. After a selected interval of time, a relay 40 operates to energize contactor 49 whereupon the actuating-coil 51 of circuit-breaker CB3 is energized, so connecting the motor M1 for full voltage operation. The energization of the trip-coil 60 for the circuit-breaker CB2 follows, in preparation for the starting of the motor M2. The push-button 201C is depressed to operate contactor 71 whereby the actuating- coil 74 for the circuit-breaker CB4 is energized, and the motor M2 is connected to the supply through reactor R and circuit-breakers CB3, CB4. A time-delay relay 87 then energizes contactor 11 which effects the closure of circuitbreaker CB2, so that both motors are now operated at full voltage. If it is intended to start the motor M2 first, the selector switch is moved to its lower position and the push-button 201C is depressed to actuate the circuit-breaker CB3. This is followed by actuation of the circuit-breakers CB4 and CB2 in timed steps. The breaker CB3 is then released and the motor M1 prepared for starting by depressing the push-button 3. The circuitbreaker CB1 is thus actuated, and the breaker CB3 is re-closed after a time-delay. In another arrangement, the motors are of the synchronous type, and the reactor R is adjacent to the switches CB1, CB4, Fig. 2 (not shown).

Title: Improvements in or relating to devices for affording protection to electric circuits
IPC: H01H73/30
Filed: 1955-01-18
Abstract: 818,561. Protective cut-out arrangements; electrically-released switches. DEWHURST & PARTNER Ltd., DEWHURST, M., WARD, A. J. C., and MINNS, G. E. Jan. 11, 1956 [Jan. 18, 1955], No. 1506/55. Class 38 (5). An overload and phase-unbalance protective device for a polyphase circuit comprises thermally responsive elements 14, substantially flat differentially movable elements 9, 10 rotatable about a common axis, and a tripping member 8 pivoted at 11 on the element 10 and coupled by a pin-and-slot connection 12, 13 to the element 9. Should the thermal elements 14 be differently heated by their heaters 1 due to phase unbalance, relative motion occurs between the elements 9, 10 against the bias of a spring 16 causing the member 8 to pivot and disengage from a shoulder 7 on a rod 6 which is moved upwardly by a spring 6 to open contacts 2, 3. When a balanced overload occurs, an ambient temperature compensating strip 17 fixed on the flat element 10 moves a loadindicating pointer 18 as the elements 9, 10 move together. When the pointer 18 abuts an adjustable stop 21 movement of the strip 17 and element 10 ceases and the continuing movement of the element 9 causes the member 8 to pivot and release the rod 6. Resetting may be effected by depressing a push-button 4 until the member 8 relatches the rod 6. The device may be used in conjunction with a contactor having auxiliary contacts in parallel with a " start " push-button. If so, the coil of the contactor may be de-energized and the contactor opened by depressing the pushbutton 4 beyond the reset position so as to open the contacts 2, 3. The various parts of the device may be mounted on three supporting plates 15, 23, 22, the plates being spaced by bosses 25, 26 on the plates 22, 15 through which bolts 24 pass, the bolts 24 serving as terminal posts for the contacts 2. The moving contact 3 is a conducting ring surrounding a split insulating bushing 32 and secured by a circlip 33. The thermal elements 14 with their heaters 1 and associated terminal posts and the scale 20 for the pointer 18 may be secured on a detachable board 39.

Title: Improvements in emergency brake and signalling devices for motor cars
IPC: B60T17/20
Filed: 1927-01-20
Abstract: 285,231. Fazekas, L. Jan. 20, 1927. Controlling independently of drivers; brakes; signalling.-An emergency braking and signalling device controlled by the passengers simultaneously operates audible and visible signals, breaks the motor ignition circuit, and releases an automatic braking device which, by means of power derived either from a rotating part of the vehicles or a spring, electric or other motor, operates the ordinary vehicle brakes intermittently and to an increasing extent. The engine being switched off also acts as a. brake. In the construction shown, a hand lever 22 in the passengers' compartment. when moved from the position shown in full lines in Fig. 1, (1) interrupts the ignition circuit 33 at 34, (2) closes parallel circuits from a battery 25 to an electric horn 26 and a signal lamp 27, at the same time lowering the lamp from within a casing 35 to a conspicuous position, and (3) rotates a detent 15 thereby permitting a push rod 14 to fall so that a catch 18 thereon is engaged by a cam 19 on the rear axle of the vehicle. The rod 14 is carried by an arm 13 controlled by a tension spring 13<1> and mounted with a small amount of lost motion on one of the brake shafts 5, so that the rod is oscillated backwards and forwards by the joint action of the cam and the spring and thereby applies the brakes intermittently. A similar lost-motion device is provided between the brake.lever-4 and its shaft 3 so that the brakes can be applied by the rod 14 without moving this lever, and a third lost-motion device is provided between one of the brake arms 8 and the shaft 5, while a double linkage 6, 7, 8 and 6<1>, 7<1>, 8<1> is employed between the shafts 3, 5, the members 6, 6<1> being tension members only. The rod 14 contains a spring buffer and is not pivoted to the arm 13 but is connected thereto by a spring pawl (not shown) so arranged that at each stroke of the rod the pawl, and therefore the corresponding end of the rod, rises on the arm 13 ; as the rod is reciprocated through a fixed distance it rocks the arm 13 through a greater angle at each stroke and thereby applies the brakes to a greater extent.
